At the start of 2026, the space industry looked, on paper, extraordinarily busy. Twenty launches and landings had been identified as the most significant events of the year — officially scheduled, publicly committed, widely anticipated. By the time the calendar reached its midpoint, only one of those twenty had actually happened: NASA's Artemis II crewed mission, which flew in April. The other nineteen had slipped, many of them now quietly rescheduled for 2027.

For an industry that routinely sells ambition, the scorecard is a sobering reminder that gravity is far easier to calculate than a reliable timeline. Against that backdrop of delay, one mission managed to move quietly but meaningfully forward. Early on Friday, a Northrop Grumman Pegasus XL rocket dropped from the belly of a modified L-1011 jetliner high above the remote Pacific Ocean, carrying Katalyst Space Technologies' Link satellite toward orbit. The launch, which had been frustrated earlier in the week by poor weather at Kwajalein Atoll in the Marshall Islands and then by a technical problem with the rocket itself on Thursday, marked the final scheduled flight of the Pegasus — an air-launched vehicle that enjoyed genuine success in the 1990s and 2000s as a small-satellite workhorse for NASA and the US military.

The Pegasus's decline tells a story that reaches well beyond any single rocket.
